On Sunday 11 July 2021, Léa Sevenig and Jack Martins Braz were crowned Miss & Mister Luxembourg 2021 at a private ceremony at the Pinacothèque museum in Luxembourg-Gare.

Hervé Lancelin, who has served as President of the National Committee Miss & Mister Luxembourg since 2017, led the coronation ceremony, which was held in private in order to comply with the health measures in force.

The 2021 jury was made up of: Hervé Lancelin, President of the Miss & Mister Luxembourg Committee; Maria Pietrangeli, Editor-in-Chief of Femmes Magazine; Claudia Vitoria Müller, Miss Luxembourg 2012; Nicolas Tissot, Member of the Miss & Mister Luxembourg Committee. The jury received assistance from Emilie Boland (Miss Luxembourg 2020), Alessandra Crescenzo (first runner-up of Miss Luxembourg 2020) and Lynn Heiderscheid (second runner-up of Miss Luxembourg 2020).

After a preselection process (nearly 85 candidates applied in recent months to the national casting), each selected candidate had to go through several stages: a general knowledge test on Luxembourg and the world, an interview with the selection panel to consider the personality of the candidates as well as a photo shoot in the three usual outfits (street, beach and evening outfit). These steps allowed the jury to distinguish the candidates and announce the final results.

Former Miss Luxembourg (2012) Claudia Vitoria Müller announced the winners at the end of the coronation ceremony.
